A set of two or more whistles. Each whistle of the set sounds differently from each other based on a different type of sound or a different value of a characteristic of sound common to whistles of the set. Sound characteristics may include but not limited to pitch, quality, loudness, and/or duration. Each whistle in the set may be different in appearance from each other in the set. Appearance characteristics may include but not limited to color, numbering, design, light up features, size, and/or shape. Alternatively, the whistles in a set may have a common appearance characteristic, but each whistle may have its own value of the common appearance characteristic. Additional element(s) such as lanyards or mouthpieces may be added to whistles of a set to distinguish them from each other. The set of whistles may be included in a kit having a box for removably storing the whistles.

There is disclosed a balloon holder for holding a balloon having a tail and a tapered self-closing bladder. The balloon holder comprises a main body having a tail locking mechanism, an elongated member protruding from a bottom extremity of the main body, a support element configured to slide over the elongated member and be positioned on the main body, and a position adjustment mechanism for adjusting the position of the support element on the main body. In use, the tail of the balloon is secured to the main body by the tail locking mechanism and the support element is slid over the elongated member and positioned on the main body using the position adjustment mechanism so as to support the balloon in an upright position.

A system and method for providing network-enabled signaling devices for sporting events are disclosed. An example embodiment is configured for: detecting an event at a sporting activity by use of a signal generator with a data processor and a sensor subsystem, the event detection being triggered by a sensor of the sensor subsystem detecting a signal exceeding a pre-defined threshold; generating a signal message including information indicative of the event detection; establishing, by use of the data processor of the signal generator, a connection with a data network; sending the signal message to a message broker via the data network; and causing the message broker to forward the signal message to subscribed subscriber platforms.

Disclosed technology allows a whistle to be magnetically detachable from a base portion, such as a finger grip. Some embodiments comprise a whistle component comprising a first magnetic member and a base component comprising a second magnetic member, such that the first and second magnetic members are magnetically attracted to each other. The whistle component can be detachable from the base component by breaking a magnetic bond between the first and second magnetic members. At least one of the first and second magnetic members can be at least partially covered by a non-magnetic material such that the non-magnetic material separates the first and second magnetic members when the whistle component is magnetically coupled to the base component. The first magnetic member can be contained within a cavity of an adaptor that is attached to the whistle, or within the whistle itself.

This invention is a new type of automotive deer whistle that produces an audible whistle. The sound that is produced can defiantly be heard by humans and wildlife. This deer whistle is made to be mounted on the front of any vehicle that exceeds the speeds 40 mph, so to prevent collisions with deer and other wildlife.

Workers who are engaged in working on equipment often require specialized equipment beyond the regular screwdrivers, pliers and wrenches. Through trial and error certain tools have been found to be invaluable, most of those combining multiple functions into a single tool. More options in a single tool mean fewer tools and lighter loads but each industry has its unique fasteners, usually to prevent unauthorized access to dangerous or proprietary equipment, such as electrical vaults and electronic hardware. Some of these tools, such as the Leatherman, are known across industries.
